This book provides an in-depth exploration of the potential impact of 6G networks on various industries, including healthcare, agriculture, transport, and national security, making it an essential resource for researchers, scholars, and students working in the field of wireless networks and high-speed data processing systems.
Development of 6G Networks and Technology explores the benefits and challenges of 5G and beyond that play a key role in the development of the next generation of internet. 6G is targeted to improve download speeds, eliminate latency, reduce congestion on mobile networks, and support advancements in technology. 6G has the potential to transform how the human, physical, and digital worlds interact with each other and the capability to support advancements in technology, such as virtual reality (VR), augmented reality (AR), the metaverse, and artificial intelligence (AI). Machine learning and deep learning modules are also an integral part of almost all automated systems where signal processing is performed at different levels. Signal processing in the form text, image, or video needs large data computational operations at the desired data rate and accuracy. Large data requires more use of IC area with embedded bulk memories that lead to power consumption. Trade-offs between power consumption, delay, and IC area are always a concern of designers and researchers. Energy-efficient, high-speed data processing is required in major areas like biomedicine and healthcare, agriculture, transport, climate change, and national security and defense. This book will provide a foundation and initial inputs for researchers, scholars, and students working in the areas of wireless networks and high-speed data processing systems. It also provides techniques, tools, and methodologies to develop next-generation internet and 6G.

Decentralized Systems and Next-Generation Internet
Series Editor: Mufti Mahmud and Suman Lata Tripathi
Scope: Next Generation Internet (NGI) is the focus of countries like the US and UK towards the improvement and revolution in the present and future internet with its backend networks and infrastructure to develop faster, reliable, secure internet platforms. The objective of NGI is to develop an advanced version of the internet. The target deliverables of NGI include building network communication architecture with enhanced levels of data access, human communication and productivity and achieving substantially and faster internet bandwidth and speed. An evolution of the internet from a low-level focus to higher level focus on interconnectivity, increased user interactions, video chat, and financial and social interactions in the virtual world are the major objectives towards development of NGI. A virtual world which is not owned or controlled by a single entity or metaverse in that a computer-generated virtual environment is created for reliable user interactions. Web 3.0 is an advancement that will control tomorrow’s internet and metaverse centers for better user experiences. In the metaverse, users interacting using software from different vendors will experience monetization by each vendor with seamless interactions in spite of different technologies.
This series covers the information from the ground level of requirements for internet-based user interactions, platforms and applications leading to the development of next-generation internet. Future requirements and dependencies on more online activities will need to work more on developing decentralized systems to improve user experience with speedy, reliable and secured interactions in a virtual environment. This series will provide the opportunity to the academician and industry professionals to share their knowledge and experiences with learners and practitioners relevant to diverse areas of improvements for the development of next-generation internet and decentralized systems or metaverse.
